Start cultivating offers now. If your current pay checks are still clearing you don't have to move in great haste. If you get an attractive offer: be as professional as you can but move on; offer to work hourly, if you can muster it, and on board new employees / contractors. Give as much notice as you think is prudent considering your new employers. If you were still enthused my advice would be different; I've spent enough time in start-ups without direction to know how frustrating and exhausting it can be. Don't languish for the sake of a broken organisation, find a healthy one and move on. I sympathise with caring about the welfare of your current employers but you can't do their job and yours at the same time.
